Hi All,
I am looking to get some insulation in my loft however the loft is fully boarded with nailed-down floorboards. I don't particularly want to go through the hassle of lifting them and then relaying them after and also a builder we got to quote reckoned that this wouldn't be a good way to go as the joists are quite shallow and banging around would probably disturb the ceilings. He also reckoned that as the current guidelines are for a 10 inch insulation layer we wouldn't be able to relay the boards anyway without compressing the insulation and compromising it. He advised us to either a) lay the insulation on top of the boards (but this would make the loft space unusable) or b) lay some other insulting material which can cope with some loft-boarding on top of it.
Does anyone out there know of these other types of insulation (he was a bit vague and I was a bit pushed for time by this point so didn't quiz him to vigorously) and what their relative merits/pitfalls are? Are there any other solutions bearing in mind we would like to use the loft space for storage etc?
Cheers
